The product box was packed carefully. A cable is also included. The box was full of bubble wrap, so I received the product in good condition. I purchased a D class amplifier and connected it; it has a nice sound quality. I'm new to amplifiers, so I don't know much about them, but the sound quality is comfortable to listen to and I like it.

The sound quality, performance, and quality are all rated as weak, but it was marked as fast, so I didn't know what it was and chose 'yes' lol. I like the product.

The box was quite wrinkled, but the internal packaging was done well so there was no damage to the product at all. They really paid attention to the packaging. The sound is good, the product design is simple, and the communication feels solid. I am satisfied.

I purchased these speakers for my bedroom system and to dip my toe into the full range sound. i have been running them for three days straight in my listening room (smallish room 3m x 6m) and every time i sit down to listen to them i am amazed at how they sound. they image wonderfully and have this purity and effortlessness through the midrange that is so addictive. i guess that’s the advantage of having no crossover. they aren’t with out their trade offs though, they can be a little peaky with some albums (notch filter helps), they don’t produce much bass (but it’s there, no slam or feel) , they sound best sitting in the sweet spot, they don’t suit all genres, and when the music gets complex or heavy they get lost a bit, but on the right music they are magic. i’m seriously considering getting a sub and making these my mains for a while or upgrading to some bigger full rangers. even with all the trade offs i think they are excellent.

The packaging was double-layered, showing attention to shock protection.
The sound quality is better than expected. The high and low tones sound very good coming from a 4-inch driver. I connected the amplifier to the Denon M40.
As expected, the sound quality of passive speakers is excellent. For a 4-inch full-range speaker, it's a sound that's beyond reproach.

The price is reasonable and the sound quality is excellent.
The case is made of walnut wood with a fine finish.
I highly recommend it.
